Extremely drug-resistant tuberculosis strain emerges in South Africa
WHO are pretty damned terrified. The real scare is how this will affect a country with the highest rates of aids infections in the world, and I've read elsewhere that this is a big concern both for the spread of the disease and the likelihood that the disease can become even more resistant.
New research findings from South Africa on an extremely drug-resistant (XDR) strain of the bacterium that causes tuberculosis (TB) alarm experts. XDR-TB is defined as resistance to three or more second line antibiotics for TB. The condition remains treatable with other types of medications, but those are less effective, costlier and toxic. If the afflicted persons can't be diagnosed timely and given proper treatment, they can die within a month. Of 53 patients who had this form of the lung infection in the study, 52 died, reports ABC News.
Dr. Tony Moll discovered the Extremely Drug Resistant Tuberculosis (XDR-TB) in the South African region KwaZulu-Natal. In an interview, he said the new variant was "very highly troubling and alarming because of the very high fatality rate." Some patients might have contracted the bug in the hospital, Dr. Moll thinks, and at least two were hospital health workers. In one year's time, an infected person may infect 10 to 15 close contacts. However, the percentage of XDR-TB in the entire group of people with tuberculosis still seems to be low; 6,000 of the total 330,000 people infected at any particular moment in South Africa.
